A Study on the Innovation of University English Teaching Mode by Integrating OBE and Mixed Reality Technology

The rapid development of virtual reality and augmented reality technology is fueling the popularity of mixed reality technology. Mixed-reality technology is becoming more and more widely used in education. The study combines mixed-reality technology with the OBE education concept and applies it to college English teaching. Human-computer interaction, graphic processing, collision detection, and other technologies construct a university English teaching system based on OBE and mixed reality. Evaluate the teaching quality of this university English teaching mode and explore the teaching effect of this mode using OBE and mixed reality through pre- and post-test comparisons. The overall score for university English teaching quality is 4.459, with a good overall level. The scores of the first-level indicators are ranked from highest to lowest: teaching process (4.682) > teaching design (4.654) > teaching effect (4.375) > teaching impact (4.124). The pre-test sig. The value of the students in the experimental group and the control group was 0.962, and the post-test sig. The value was 0.001. The difference between the pre-test and post-test scores of the experimental group on the dimensions was higher than that of the control group by 4.69, 3.74, 2.70, 2.50, and 13.63 points, respectively. The university’s English teaching model based on OBE and mixed reality has a significant effect on improving students’ English proficiency. The score difference between OBE and Mixed Reality-based university English teaching mode and traditional English teaching mode in terms of the sense of experience ranges from 1.33 to 3.01. In addition to the sense of authenticity, the sense of experience of OBE and Mixed Reality-based university English teaching modes is significantly better than that of traditional English teaching modes.
